Release Notes for BayStack Operating System Switching Software (BoSS) 3.1
Explanation
The unit did not receive any acknowledgment when it communicates
with its downstream unit.
Diagnostic Info
First, determine whether you have a bad cable or bad downstream
unit. If the cable connecting to the OUT stack port is bad, the stack
port on both ends of the cable should be wrapped out and the units
attached to the cable should still be in stack. Also, the unit that is
attached to the other end of the cable should have the following
system log entry, "IN stack port wrapped; check for bad cable or unit".
Replace the cable with a good one, and reboot the units that were
attached to this cable. On the other hand, if the downstream unit is
bad, the downstream led on the downstream unit should be amber
and the downstream unit is not in stack. Replace the downstream
stack module or downstream unit.
Table 20
Log Entry
Stack manager event MODULE INACTIVE (module id = <physical
id>)
Explanation
Informational message declaring that the module < module mask>
has become inactive because it did not receive the necessary
heartbeat packets.
Diagnostic Info
You need to find out why heartbeats are not getting to this unit
<physical id>. Make sure that the unit is connected to the stack
properly and the cascading connectors are screwed in all the way. If
you just powered off the module, then this log is expected to show up.
Table 21
Log Entry
Stack manager event BECOME TEMP BU (module id <physical id>)
Explanation
Informational message declaring the unit has become the base unit
due to the heartbeat packets not being received from the former base
unit.
Diagnostic Info
Make sure that the former base unit is still operational. Typically,
when the base unit goes out for more than 30 seconds, a temporary
base unit will take over.
